摘要
本文针对典型合成气燃烧的详细化学动力学机理进行了系统的验证和分析。通过不同反应机理对点火延迟时间和层流火焰速度的预测,研究和分析了不同反应机理的区别和模拟结果的可靠性。采用强制敏感度分析方法揭示了影响合成气点火延迟时间和层流火焰速度的重要反应,并对相关反应的动力学进行了分析讨论,为进一步构建统一可靠的燃烧反应机理奠定了基础。
Detailed reaction mechanisms for syngas combustion are validated and analyzed in the present work. According to the predictions of ignition delay time and laminar flame speed by employing contemporary combustion mechanisms, the differences among these mechanisms are presented and their robustness for numerical simulations are validated. Further, on the basis of sensitivity analysis, important reactions which greatly affect the ignition and laminar flame speed are identified, and related reaction rate constants are discussed. The present work provides fundamental information for further development of a universal reaction mechanism for syngas combustion.
